WHY YOU NEED IT
Helical piers provide excellent and affordable foundation solutions for both residential and commercial projects where problematic soil conditions exist or where there is limited access to the site. Advantages for using helical piers over other piering systems are:
- Fast installation
- No vibration during installation
- Can eliminate grade beams at pile cap locations
- Ease of installation in limited access areas (where cranes cannot be mobilized)
- Minimum disturbance to site
- No excavation is required
- All galvanized steel foundation
- Immediate structure installation
- All weather installation
- On-site load test capability
- 30 year transferrable materials warranty
WHAT IS IT?
Helical piles are square or round shaft galvanized steel piles that screw into the ground. They are incorporated into other foundation elements like footings, pile caps or structural slabs and can provide load and/or uplift capacities up to 100 tons. They are approved by national building code agencies BOCA, ICBO, SBCCI, CCMC and ICC, the CHANCE® helical pier and tension anchor has become the deep foundation system of choice for architects, builders, contractors, engineers and geotechnical firms.
METHODOLOGY AND INSTALLATION
Each pier is designed by our engineers to perform based on the required loads and soil conditions for your project. Helical piers are quickly installed either with a mini-excavator or, in limited space applications, can be installed with a hand-held device. The process starts with gathering data about your existing soil and structure's condition
- TESTING AND DESIGN: for most projects, the design process occurs with gathering information about your project:
- We obtain soils information from a geotechnical engineer to define the soil conditions
- A structural engineer works with us to define the necessary capacity of the piles, the pile type and configuration based on the soils report and existing structural conditions
- A plan is created to resolve the settled condition of the structure and a permit is applied for.
- IMPLEMENTATION: We mobilize onto your site and review the scope of work with you The workmen are careful to protect surroundings and clean up as work proceeds. The site is left in a safe and clean condition at the end of each workday. The installation of the piers is documented and any variances are discussed with the engineer of record. At the end of the project, we review the site conditions with you to ensure the site is being left as planned. We also offer full-service cosmetic and remodeling repairs to our clientele.
- FINALIZATION: Installation logs are kept for each pier and reviewed by the engineer of record. The logs keep track of the total depth achieved of the pier and pressures encountered during installation. The logs are submitted to the building department along with a Certificate of Completion from the engineer to certify that our installation was in compliance with the plan. The installation ends at this point; the permit is finalized and you can rest assured that you have installed a strong foundation.
HOW THEY ARE USED
- Helical piers: residential and commercial building foundations, equipment stands, communication tower foundations, temporary foundations, pool shell hold-downs
- Pull-down piers: grouted helicals to reduce buckling in loose soils
- Excavation walls: to allow deep excavations next to existing structures
- Tie backs: reinforce seawalls, retaining walls and basement walls
- Slab piers: support for structural slabs
BENEFITS
Fast, reliable and affordable foundation solutions with a transferable 30 year warranty.
